t I I rmED PAYNE MARTIN, OFOTTAWA, KANSAS.

To all whomz't may concern: I I I Be it known that I, FRED P. MARTIN, a

citizen of the United States, residing at -Ottawa, in. the county ofFranklin and State of Kansas, have invented a new and usefulCulvert-Form, of which the following is a specification. I i I Thedevice forming the subject matter of thisapplication' is adapted to beemployed for supporting a, form of the kind on which arches, culvertsandthe like are built, the device being of peculiar utility when concretestructures are being erected.

The device is in the form of an arch,-either of rectangular or curvedoutline, and it is one object of the invention to secure, by a simplemeans, the necessary adjustments k both as to outline and as todimensions.

I Another object of the invention is toIprovide an arch the parts ofwhich may be interchanged readily to permit the necessary variations inthe size and form of the struc- .ture. I

' Another object ofthe invention is to provide a device of the sortmentioned in which lightness will be combined with the necessarystrength, the constituent members of the arch being so constructed andbraced thatthis result will be brought about. 0.. It is'within theprovince of the disclosure to improve generally and to enhance theutility of devices of that type towhich the invention appertains.

With the above andv other objectsin view which will appear. as thedescription proceeds, the invention resides in the comblnadetails ofconstruction hereinafter described and claimed, it being understood thatchanges in the precise embodiment of the invention herein disclosed,'canbe made within the scope of what is claimed, without departing from thespiritof the invention.

atop plan of the structure dewhich forms a connection between the foot Iand the arch proper. v n

The structure hereinafter described and claimed preferably but notnecessarily is made of metal throughout, and as-disclosed in Figs. 1, 2,3 and 4, includes a foot 1, a

foot 2, single-wall supports 3, double-wall supports 4, a double-wallcorner member 5,

a single-wall corner member 6, and a complate 7 which, if desired, maybe omitted. I I

The foot 1: comprises a base 8 and, upstanding Wings9, the foot 2including a base 10 and a single upstandingwing 11.

The double-wall supports :4 each include frames 12 having extensions 14at their cor- Braces 15 converge from two corners of each frame 12 andunite with each other,

,. and with the oppositeside of the frame, at

a point approximately half way between the ends of; said side. oftheframe. The constituent members of the supports 4 may be united byintegral pin-like connections 16, 12, others The support 3 is in theform of a frame 17 having braces 18 disposed like the braces 15, theframe 17 having extensions 19 at its corners. ,tion and arrangement ofparts and in the The double-wall cornerinember 5 includes a pair of;open frames each comprising a 1 means ofa transverse arm 25 merging intoa hub 26,from which radiatebraces 27 extendedto two corners of the frameand corresponding to the braces 18 and 15. The constituent frames of thedouble-wall corner member 5 are united by spaced, integral pinlikeconnections 28,; corresponding to the parts 16. Atitslowercorners, themember- I 5 is provided with extensions 29. The single-wall cornermember 6 includes an O terside a 3.0, a top ba 1, bo om ba 32, and aninner side bar. The inner side bar includes a lower part 33, an upperpart 3% offset from the lower part33, and a transverse arm 36 connectingthe parts 33 and 341.. The said arm 36 merges into a hub 35from V plate7 is of singlethickness as shown at ll, but at its inner end,bifurcations 42 are formed, the bifurcations being united by connections43 constructed like the connections 16 hereinbefore alluded to. At thecorners of the compromise plate 7,'ei rtensions 44 are fashioned. Ashereinbefore stated, the compromise plate? may be omitted,but it will befound to be a useful adjunct.

The various elements above describedmay be duplicated to any desiredextent, depending upon the size and contour ofthestructure. Manycombinations maybe made up, and it is impossible to describe allof-them. A single method of combining the various parts "willbedescribed, others suggesting themselvesreadily to the user-when theconstruction and operation of the device is understood. The constituentmembers of the structure are united by removable pins 45 extendingthrough the extensions of -which the parts 29 and 19 nay'be'taken astypical.

' In the drawings, the single-wall support 3 ismounted between wings?!)of the root 1, the upper end of the support 3 being received between theparts of-the double-wall corner member 5. A single wall support 3 isreceived at one end betweenparts of the cornerinember 5, the support3co6perates with a double-wheel support 4, the doublewheel support 4coacts with the part d1 of the compromise plate 7, the bifurcations 42of the compromise plate coa'ct with the single wall corner member 6, theI single-wall corner member6 is engaged with a'doublewall support 4:,and the latter, atits lower end, is assembled with the wing 11 of thefoot 2. The foregoing is a siinplecombination in which all of thevarious parts of the device are used, but it will be appreciated that byduplicating and rearranging the constituent members, 'an almost endlessvariety of combinations may be' nade up, permitting variations both asto size'and'as to contour. p i In Figs. 5 to 8, a modified form of theinvention has been shown, the modification consisting in adapting thestructure to form a supporting means of curved outline. Since the deviceshown in Figs. 5 to 8 1s const ucterligenc y like the struct of Fig. 1,the description may be shortened con ide ably- As shown in Figs. 5 to 8,feet 46 are employed, each foot including a base &7 and wings 48sustained by braces 19. A plate 5,0,is mounted between the wingsflg, tlie upper edge of the plate being curved as shown atbl soas to correspondto the curved outer edges 61 of the wings 4:8. The plate 50 forms aconnection between-thefoOt 46 and the arch proper,theupper or inner endof the plate' 50 being received' between the walls :52 of-adouble-walled memberfthe parts of which are-unitedby-identicalconnections 53. There are openings "54 iin -the plate 50,suitably numbered for identification, and adapted' to receive pins55'whereby the plate may be connected to the -wings 48 ofthe -foot4i6and to the-walls 52 of=the arch member, therebeinga plurality ofopenings56 in the archmemberarid there being-a plurality of openings 62 in" thewings '48 ofthe foot 46, to ermit of the necessary adjustment. 7 The aouble-walled -arch inember coacts witha single-wallarchdmember 57, theseparts *being connected by pins 58, the construction above describedbeing duplicated amtil the opposite 'foot 46 is reached The variousarehmembers are in the form-of open frames, reinforced by-internal braces60, thearch members being curved on their outer edges as shown at 59, soas :to cooperate with the -'edge 51 of the plate '50, and with the edgesblot the wings 48. I I

In both forms'of-the invention,it is.possible to make I the necessaryadjustments to secure variationsin the-size and contour or thestructure, and in both forms-ofthe invention, lightness is combined'withstrength.

Reverting to Fig. 1, it Will be observed that since the parts Qet and 34of the corner members 5 and '6 are set outwardlyfthe thrust from the toppartof the arch will be carried downwardly within the contour of thefeet 1 and2 and, owing to the presence of the braces 27 and '37, thecdrn'er members will possess the requisite strength. Having thusdescribed th invention,

what is claimed is:

1. A device-of the class-described 'includ' ing feet, and an archextended between the feet, the arch comprising single-wall anddouble-wall membersfthe ends'of the singlewall members i being receivedbet een the ends of the double wall members,all of the members of thearch being in the form of =open frames having transverse internalbraces, the walls of the double-Walhn embers being united by integralspaced pinlike connections; removable-pins connect-in the inner andouter portions of the terminal members of the arch with the feet; andremovable pins connecting the coa'cting ends of the arch memberstogether.

2; A device of the class described, of rectangular outline, andincluding feet, corner members, supports detachably uniting the feetwith the corner members, and other supports detachably connected witheach other, the supports being in the form of open frames, the cornermembers each including an inner side bar comprising a lower part, anupper part, and an arm connecting said parts, the upper part being 00,1"of this patent may be obtained for five cents each, by addressing the"commissioner of Patentl,

set outwardly with respect to the lower part, the terminal ones of saidother supports being detachably connected with the upper parts of theinner side bars of the corner members to bring the downward thrustwithin the contour of the feet.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.
